http://backpack.tf/profiles/76561198011916095#!/compare/1483488000/1483833600 - Sold for a Steaming Beak
http://www.tf2outpost.com/trade/28697510 - Took just a day, B/O was 30
I can't find a good mini for the Beak, but there are multiple buyers for 28, so it would have to be higher than that.
https://backpack.tf/profiles/76561198067662784#!/compare/1482796800/1482883200 - Added 11 pure for a PE Whoopee, the 2 extra keys were spent on the Scatter skin, which was a separate trade
Also, your sale #3 and sale #4 are just the same sale seen from buyer's side and seller's side.
Closing. Feel free to take it.
